The cull of tahr in the Southern Alps will be unlikely before February after the death of two experienced hunters.
The operation has been on hold since Department of Conservation workers Scott Theobald and Paul Hondelink died in a helicopter crash in Wanaka last month.
Doc lead operations director for tahr control Andy Roberts said no new date had been set for the operation, but it would be unlikely before February.
Numbers of tahr would continue to increase while the operation was on hold, he said.
"Doc is still planning to reduce the population by 10,000 before 31 August 2019 as part of Doc's Tahr Control Operational Plan."
